  • Decorative hook mesh size width generally does not span 2 meters. Generally, the length does not span 4m. The length of 2 meters is difficult for workers, and the second is that the galvanized plating is not good. It can reach up to six meters in length, but it doesn’t cross six meters. Generally, the price will increase significantly after 4 meters.

  • Moderate rates of foam formation may be harmless. The presence of small, homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of excessive solid particles can cause an explosion.

  • Steel wire mesh by its own unique advantages in construction occupation, reinforcement anti-crack occupation is indispensable reinforcement anti-crack data, high product error is small, mesh mesh uniform, welding firm, strong acceptance, not easy to deformation, steel wire mesh in different fields have different called, in bridge engineering construction people call it soft reinforcement.

  • The production process of stainless steel blade barbed wire is basically similar to that of galvanized blade barbed wire, and the blade size is usually determined according to the mold.

  • The vertical distance between the lower edge of the Nestor roller cage and the upper edge of the reinforced concrete protective fence is 0.05m. Longitudinal reinforcement adopts hot-dip galvanized netting, double-twist weaving process, barbed wire 2.2mm, main line 2.5mm, netting joint card adopts galvanized steel plate stamping or Q235 carbon steel plate stamping for galvanized.

  • 1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.

  • Product features: strong structure, flat surface, with good corrosion resistance, oxidation resistance.

  • Hot-dip galvanized hexagonal net is another way of twisting hexagonal net corresponding to galvanizing.

  • 5. The bird cage should be sprayed with transparent wood environmental protection paint every 1-2 years. This protects the cage’s skeleton from the effects of weathering.

  • Maintenance is indispensable in the use of galvanized wire. Large coils of galvanized silk should be coated with oil, fiber core immersion oil, oil is required to protect the fiber core is not rotten, not rust, wire moisture fiber, and from the internal lubrication wire rope. Surface coating so that all wire rope strands in the surface, are evenly coated with a layer of rust-proof lubrication grease, which for friction lifting and mineral water large mine rope, to be coated with grinding and water-resistant black oil grease. Coated with red oil with strong film and good rust resistance, it is required to have a thin oil layer, which is easy to keep clean during operation.

  • One is to do a good job of galvanized wire packaging, avoid bump, to ensure the integrity of the zinc layer;

  • Plastic paint is often see way of electrostatic daub, can be fixed on the periphery of the barbed wire or iron wire board, requires two baidu after heat treatment, make plastic paint or powder coating adhesive on the wire plate, these are painted plastic razor wire is commonly used in indoor boxes, plastic paint surface look overall feeling is very good, strong adhesive force, at the same time is more durable, Coating processing does not take too long, mainly rust prevention and corrosion effect is quite good, much better than the general material.

  • On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.

  • Poor pretreatment before plating; Bath temperature is too low; Poor quality of additives or too many additives and organic impurities will cause poor bonding. The quality of additives also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the crystal lattice and cause stress, causing the coating to bubble.

  • The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the attraction between the atoms is relatively small.

  • Weaving and features: mesh uniform, flat, woven, crocheted, beautiful and generous; Good mesh, wide mesh, coarse diameter, not easy to corrosion, long life, strong usefulness. Usefulness: widely used in highway, railway, highway and other guardrail equipment. To choose the hook mesh permeability special effect, a large area of application in mountain protection, used to fix the rock, together with the selection of green grass spray to reach the late curing effect. It is a perfect separation of greening and protection.

  • As we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:

  • Copper sulfate point test is a simple way to quickly distinguish ordinary carbon steel and all types of stainless steel wire rope. The concentration of copper sulfate solution used is 5%-10%. Before the point test, the experimental area should be thoroughly removed from the oil or other impurities, and a small area should be polished by grinding machine or soft grinding cloth, and then the test liquid drops to the grinding place. Ordinary carbon steel or iron in a few seconds will form a layer of outer metal copper, and the surface of stainless steel does not produce copper precipitation or display copper color.
